SPECIFICATION forming part of Letters Patent No. 779,946, dated January10, 1905.

Application led October 1,1903. SerialvNo. 175,278.

To all whom, it Uta/y concern.'

Be it known that I, OLIVER LINK, a citizen of the United States,residing at St. Charles, Missouri, have in vented acertain new anduseful Improvement in Rotary Funnel-Cocks,of which the following is afull, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same,referencebeing had to the accompanying drawing, forming part of thisspecilication.

This invention relates to a new and useful improvement in funnel-cocksfor car-heating apparatus, the object being to construct a device of thecharacter described which is simple and cheap in construction and whichwill protect the system from the entrance of dirt and dust at thispoint, said funnel-cock being' combined with an ordinary cock having avent which is opened coincidently with the opening of the ordinary cockto admit water into'the system.

I/Vith these objects in View the invention consists in the construction,arrangement, and combination of the several parts, all as will behereinafter described and afterward pointed out in the claim.

The cock shown in the drawing is designed to be attached in position toa tank usually arranged on top of the coach, and the casing or shell isprovided with a threaded nipple l to effect this attachment.

2 is a rotatable plug-cock'having a passag'e 8, which is designed toopen and close communication from the funnel-cock to the tank, saidplug-cock also having a passage 4, which is designed to register withpassages 5 and 6, the former opening to the exterior and the latter tothe interior of the tank, whereby when the plug-cock opens communicationbetween the funnel-cock and the interior of the tank the vent-openings4:, 5, and 6 will be in registration for well-understood purposes.

7 is a handle on the plug-cock for operating the same. r

8 is a hollow extension or boss having atapered outer face, through theupper face of which opens a port 9 and through whose lower face opens aport 9a. On this tapered projection is mounted the hub IO of a funnel1l, the same being held in position by a nut secured on the threadedextension of said hollow projection. When the funnel is in an uprightposition, as shown in full lines, and the 'plug-cock is rotated to opencommunication with the interior of the tank and coincidently open thevent-passages, water poured into the funnel will be conducted to theinterior of the tank, as will be readily understood.

In practice usually a surplus of water is introduced into the tank, andthis is indicated by the water overfiowing the vent-opening. When thisstage is reached, the funnel is turned from its upright position to itslower position, so that the surplus water in the tank will escapethrough the port 9a. When the proper water-level is reached, theplugcock is turned to close communication between the tank and theexterior, both with respect to the water-passage of the vent-opening.

I am aware that minor1 changes in the construction, arrangement, andcombination of the several parts of my device can be made andsubstituted for those herein shown and described without in the leastdeparting' from the nature and principle of my invention.

Having thus described the invention, what is claimed as new, and desiredto be secured r by Letters Patent, is-

In a iiller-cock for water-heaters, the combination with a valve-casing,the outer end of which is provided with a conical wall having a threadedprojection at one end, said casing having two longitudinally-arrangedports, one of which is provided for the passage of air and water and theother for the passage of water, the rst-named port being above the otherand extending in a straight line longitudinally through the casing, sothat all parts of the port are in alinement with each other, a plugarranged in the casing and intersecting the iirst-named port and havingan opening alining with the opening in the yplug below the Elrst-namedopening therein, said second-named opening alining with the lowerWater-port, the casing being' provided with a transverse channel at theend of thelower signature,inthepresenceoftwo Witnesses,this plort, aconica leeve fitting over one end of 23d day of September, 1903. t ecasing an mving an opening for registration with oppositely-disposeddischarge- OLIVER LINK' 5 ports therein, and a funnel Carried by theWitnesses:
